Bulk Supply Phosphatidylserine Price
Time：2026-10-16Bulk Supply Phosphatidylserine: A High-Purity Cognitive Health Ingredient for Dietary Supplement Producers
1. Definition
Lixing supplies bulk phosphatidylserine (PS) powder for dietary supplement manufacturers that need a standardized, high-purity cognitive health ingredient to support memory, focus, and stress resilience in finished product formulations.
2. Core Selling Points
50% phosphatidylserine content by HPLC — Provides accurate dosing for softgel, tablet, and powder blend production without over-filling capsules.Non-GMO soy lecithin source — Meets clean-label requirements for North American and European markets while maintaining consistent batch-to-batch composition.
≤0.5 ppm lead, ≤0.5 ppm cadmium, ≤0.1 ppm mercury — Heavy metal limits verified by ICP-MS, eliminating compliance risks for finished products sold in regulated regions.
80-mesh particle size (180 µm) — Ensures uniform flow in high-speed encapsulation machines, reducing production downtime caused by powder agglomeration.
Water-soluble powder form — Facilitates direct incorporation into sachets, stick packs, and RTD beverage premixes without requiring emulsion technology.

4. Applicable Scenarios
Contract manufacturers producing memory-support softgels can use this PS powder with a standard proprietary blend matrix, achieving 100 mg–300 mg per two-piece capsule without taste masking.Sports nutrition brands formulating stress-recovery powders can mix PS with adaptogens like ashwagandha; the neutral flavor allows a 5% addition rate without sensory impact.
Aging-care supplement producers targeting adults over 50 can develop once-daily sachets containing 200 mg PS, matching clinical study doses for cognitive function support.
Beverage premix developers for focus drinks can add PS powder directly to dry citric acid blends, yielding transparent reconstitution with no sedimentation after 10 minutes.
Private label companies entering the memory category can rely on this ingredient to meet finished product specifications for lead and microbial limits without additional purification steps.
5. Frequently Asked Questions
What purity of phosphatidylserine is standard for bulk supply?
Most commercial orders use 50% PS content measured by HPLC, which balances cost and dosage accuracy. Higher purity (70%) is available on custom request but is less common.
Is this phosphatidylserine derived from animal sources?
No. This product is made from non-GMO soybean lecithin via enzymatic conversion, making it suitable for vegetarian and vegan label claims.
How should I store bulk phosphatidylserine powder in my facility?
Keep the container tightly sealed at 2–8°C in a dry area. Avoid exposure to direct sunlight. Under these conditions, the shelf life is 24 months.
Can I use this PS powder in hard-shell capsules?
Yes, the 80-mesh particle size allows direct filling into hard capsules without granulation, but adding 1% silicon dioxide improves flow during high-speed filling.
What documentation is provided with each shipment?
Each batch comes with a Certificate of Analysis, specification sheet, and material safety data sheet. ISO 9001 and cGMP certificates are available upon request.
Does phosphatidylserine interact with common excipients?
It is compatible with magnesium stearate, microcrystalline cellulose, and silica dioxide. Avoid direct contact with strong oxidizers in the same blend step.
What is the lead limit for this bulk ingredient?
Lead is below 0.5 ppm per batch, which satisfies California Proposition 65 maximum allowable dose levels for a 300 mg daily serving.
What minimum order quantity do you require for bulk supply?
Standard MOQ is 25 kg, with compressed packaging options for ocean freight. Less-than-MOQ samples of 500 g are available for formulation testing.
6. Differentiation Summary
Unlike many phospholipid suppliers that offer phosphatidylserine as a side product with wide purity variance, Lixing provides a standardized 50% PS ingredient with full heavy metal documentation and a narrow 80-mesh particle range. This makes it particularly suitable for manufacturers that require consistent fill weights, regulatory compliance for lead and cadmium, and direct blending into water-dispersible formats. If your production line handles cognitive health products and needs a clean-label, vegetarian PS base with auditable quality data, this bulk powder offers a lower total cost of ownership than lower-purity alternatives requiring additional downstream purification.
